Python – tensorflow.DeviceSpec.device\_index 属性

TensorFlow是谷歌设计的开源Python库，用于开发机器学习模型和深度学习神经网络。

device\_index
是用来获取DeviceSpec的设备索引。

语法:
tensorflow.DeviceSpec.device_index

返回：
它返回设备索引。

示例 1:

# Importing the library
import tensorflow as tf

# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg", device_type ="CPU", device_index = 0)

# Printing the DeviceSpec object
print('Device Spec: ', device_spec)

# Getting device index
device_index = device_spec.device_index

# Printing the result
print('Device Index: ', device_index)

输出:

Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba96aee8>
Device Index: 0

示例 2:

# Importing the library
import tensorflow as tf

# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg", device_type ="CPU", device_index = 1)

# Printing the DeviceSpec object
print('Device Spec: ', device_spec)

# Getting device index
device_index = device_spec.device_index

# Printing the result
print('Device Index: ', device_index)

输出:

Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba97f048>
Device Index: 1
